I'll never understand why I'm still treated like a preteen

How this morning's conversation (right after I woke up) could have gone:
Mom: *knocks on door*
Me: Come in.
"How was Chrissy's?"
"It was good."
"What movie did you guys see?"
"Inception, it was pretty good."
"How's her mom doing?"
"She seemed to be doing fine."
"That's good."

How this morning's conversation (right after I woke up) actually went:
Mom: *walks in without knocking* "What time did you get home last night."
Me: "Like around 3."
"You shouldn't be staying out that late."
"Okay well we were just at Chrissy's..."
"There are weirdos out on the roads that late."
"Um there was no one on the road."
"It's hot in here."
"...okay?"

So now I have a curfew again. And I'm a month out from being 22. Get me the hell out of here.

In other really good news, I lost three job opportunities because I was on a bullshit vacation. COOL.
